Protocolo diagnóstico de la afectación hepática en las enfermedades autoinmunes sistémicas

Abstract

Systemic autoimmune diseases are conditions in which there is an alteration of the immune system that is chronic and with multisystemic involvement. Due to its central role in metabolism, the liver is often affected to varying degrees. There are different mechanisms that can explain this involvement. First, immune dysregulation itself can lead to direct liver toxicity (antibody formation, T cell-mediated injury), as well as the development of primary liver disease (autoimmune hepatitis, primary biliary cholangitis). Second, patients with autoimmune diseases can develop different forms of hepatic vascular involvement such as porto-sinusoidal vascular disease, sinusoidal obstruction syndrome, Budd-Chiari syndrome, or the onset of hepatic ischemia within vasculitis. Finally, the drugs used in the treatment of systemic autoimmune disease can produce hepatotoxicity through different mechanisms, some of which are not fully known.
